This attempts to set up built-in "git grep" to further reduce
our dependence on the shell, while at the same time optionally
allowing to run grep against object database. You could do
funky things like these:
git grep --cached -e pattern ;# grep from index
git grep -e pattern master ;# or in a rev
git grep -e pattern master next ;# or in multiple revs
git grep -e pattern pu^@ ;# even like this with an
;# extension from another topic ;-)
git grep -e pattern master..next ;# or even from rev ranges
git grep -e pattern master~20:Documentation
;# or an arbitrary tree
git grep -e pattern next:git-commit.sh
;# or an arbitrary blob
Right now, it does not understand and/or obey many options grep
should accept, and the pattern must be given with -e option due
to the way the parameter parser is structured, both of which
obviously need to be fixed for usability.
But this is going in the right direction. The shell script
version is one of the worst Portability offender in the git
barebone Porcelainish; it uses xargs -0 to pass paths around and
shell arrays to sift flags and parameters.

Earlier patch to say <ent>:<path> by Linus was very useful, and
this extends the same idea to the current index. An sha1
expression :<path> extracts the object name for the named path
from the current index.

A short-hand "rev^@" is understood to be "all parents of the
named commit" with this patch. So you can do
git show v1.0.0^@
to view the parents of a merge commit,
gitk ^v1.0.0^@ v1.0.4
to view the log between two revs (including the bottom one), and
git diff --cc v1.1.0 v1.0.0^@
to inspect what got changed from the merge parents of v1.0.0 to v1.1.0.
This might be just my shiny new toy that is not very useful in
practice. I needed it to do the multi-tree diff on Len's
infamous 12-way Octopus; typing "diff --cc funmerge funmerge^1
funmerge^2 funmerge^3 ..." was too painful.
[jc: taking suggestions from Linus and Johannes to match expectations
from shell users who are used to see $@ or $* either of which makes
sense. I tend to write "$@" more often so...]

You can now select whether you want to see the patch for a commit
or the whole tree. If you select the tree, gitk will now display
the commit message plus the contents of one file in the bottom-left
pane, when you click on the name of the file in the bottom-right pane.

The C'ification of push left these behind.

This adds a builtin "push" command, which is largely just a C'ification of
the "git-push.sh" script.
Now, the reason I did it as a built-in is partly because it's yet another
step on relying less on shell, but it's actually mostly because I've
wanted to be able to push to _multiple_ repositories, and the most obvious
and simplest interface for that would seem be to just have a "remotes"
file that has multiple URL entries.
(For "pull", having multiple entries should either just select the first
one, or you could fall back on the others on failure - your choice).
And quite frankly, it just became too damn messy to do that in shell.
Besides, we actually have a fair amount of infrastructure in C, so it just
wasn't that hard to do.
Of course, this is almost totally untested. It probably doesn't work for
anything but the one trial I threw at it. "Simple" doesn't necessarily
mean "obviously correct".

"git diff(n)" without --base, --ours, etc. defaults to --cc,
which usually is the same as -p unless you are in the middle of
a conflicted merge, just like the shell script version.
"git diff(n) blobA blobB path" complains and dies.
"git diff(n) tree0 tree1 tree2...treeN" does combined diff that
shows a merge of tree1..treeN to result in tree0.
Giving "-c" option to any command that defaults to "--cc" turns
off dense-combined flag.

This brings another small repacking speedup for sensibly the same pack
size. On the Linux kernel repo, git-repack -a -f is 3.7% faster for a
0.4% larger pack.

attention.
This also eliminate the issue of adler32() reading past the data buffer,

After doing the hard work of hand resolving the conflicts in the
working tree, if the user forgets to run update-index to mark
the paths that have been resolved, the command gave an
unfriendly "fatal: git-write-tree: not able to write tree" error
message. Catch the situation early and give more meaningful
message and suggestion.

We used to omit delta base candidates that is much bigger than
the target, but delta size does not grow when we delete more, so
that was not a very good heuristics.

When I split out the builtin commands into their own files, I left the
include of <sys/ioctl.h> in git.c rather than moving it to the file that
needed it (builtin-help.c).
Nobody seems to have noticed, because everything still worked, but because
the TIOCGWINSZ macro was now no longer defined when compiling the
"term_columns()" function, it would no longer automatically notice the
terminal size unless your system used the ancient "COLUMNS" environment
variable approach.
Trivially fixed by just moving the header include to the file that
actually needs it.

This lets us do things like highlighting all the entries for which
the corresponding part of the diff is at least partly visible in the
commit/patch display window, and in future it will let us display

* jc/cache-tree:
read-tree: teach 1-way merege and plain read to prime cache-tree.
read-tree: teach 1 and 2 way merges about cache-tree.
update-index: when --unresolve, smudge the relevant cache-tree entries.
This teaches read-tree to fully populate valid cache-tree when
reading a tree from scratch, or reading a single tree into an
existing index, reusing only the cached stat information (i.e.
one-way merge). We have already taught update-index about cache-tree,
so "git checkout" followed by updates to a few path followed by
a "git commit" would become very efficient.
Signed-off-by: Junio C Hamano <junkio@cox.net>
This teaches one-way and two-way "read-tree -m" (and its special
form, "read-tree --reset" as well) not to discard cache-tree but
invalidate only the changed parts of the tree. When switching
between related branches, this helps the eventual commit
(i.e. write-tree) by keeping cache-tree valid as much as
possible.
This does not prime cache-tree yet, but we ought to be able to
do that for no-merge (i.e. reading from a tree object) case and,
and also perhaps 1 way merge case.
With this patch applied, switching between the tip of Linux 2.6
kernel tree and a branch that touches one path (fs/ext3/Makefile)
from it invalidates only 3 paths out of 1201 cache-tree entries
in the index, and subsequent write-tree takes about a half as
much time as before.
